About the Airtac SCJ80 Standard Cylinder SCJ80X10-10S
The SCJ80X10-10S is an 80 mm bore, double-acting single-rod cylinder with a field-adjustable stroke end, delivering 2513 N of push force at 0.5 MPa. A rear-cap adjusting screw provides up to 10 mm of stroke-end reduction, letting you fine-tune the piston stop position during commissioning or format changes without replacing the cylinder.
This model includes a built-in magnet (-S), so CMSG/DMSG/EMSG reed or solid-state sensors clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. It uses a 25 mm diameter piston rod, PT3/8 ports, and an M20x1.5 rod thread. The standard TPU seal operates from -20 to +70 °C, and the 28 mm air cushion decelerates the piston quietly at stroke end.
Airtac SCJ80 Standard Cylinder SCJ80X10-10S Technical Specifications
| Model | Airtac SCJ80 Standard Cylinder SCJ80X10-10S |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø80 mm |
| Nominal stroke | 10 mm |
| Stroke adjustment | Up to 10 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 28 mm |
| Max stroke | Up to 1500 mm |
Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCJ80 Standard Cylinder SCJ80X10-10S Is Used
End-Stop Calibration
The 10 mm adjusting screw allows operators to dial in the exact retract stop position on a clamping fixture, compensating for part tolerance stack-up without reprogramming the machine controller.
Short-Throw Ejectors
Delivers a powerful 2513 N push in a compact 10 mm stroke, with the adjustable end position preventing impact damage on delicate parts during high-speed ejection from a forming die.
Wear Take-Up on Stops
As a mechanical end-stop pad wears over thousands of cycles, the SCJ's rear screw can be advanced slightly to restore the original stopping position, extending the service interval of the tooling.
Is the Airtac SCJ80 Standard Cylinder SCJ80X10-10S the Right Cylinder?
Choose the SCJ80X10-10S when your application needs a short 10 mm nominal stroke that can be trimmed down to zero by the 10 mm adjusting screw—ideal for precise end-stop setting on clamps or ejectors. If you require more force, step up to the 100 mm bore (3927 N push at 0.5 MPa); for a lighter, more compact solution, the 63 mm bore offers 1559 N.
For replacement, match an AirTAC SCJ adjustable-stroke cylinder with an 80 mm bore, 10 mm nominal stroke, 10 mm adjust range, PT3/8 ports, basic mounting, and a built-in magnet. If the stroke never needs field adjustment, a fixed-stroke SC80X10-S cylinder is a simpler alternative.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ80 Standard Cylinder SCJ80X10-10S FAQ
At 0.5 MPa, it produces 2513 N pushing and 2268 N pulling. The force increases linearly with pressure, reaching 4523 N push at the maximum operating pressure of 0.9 MPa. Because it is a single-rod cylinder, the pull force is always lower due to the 25 mm rod reducing the effective piston area on the retract side.
A screw in the rear cap mechanically limits how far the piston can retract, shortening the stroke end by up to 10 mm. It only sets the end position; it does not lock the piston. If air pressure is lost or the valve is centered, the rod can drift. For load holding without pressure, you must add an external rod lock or a pilot-operated check valve.
